Holger Haljand from EMT AS / TeliaSonera Estonia gave a presentation on Estonia's experience with electronic, digital and mobile identification. Estonia has implemented ID cards, mobile ID using SIM cards, and digital signatures to enable widespread e-government, e-banking, e-voting and other online services. Mobile ID offers a simple, convenient authentication method without needing readers or software. Lessons from Estonia show that usability and a strong ecosystem of online services are key to high adoption of mobile ID. The future of identification lies in mobile solutions that can be used across more devices and countries.
